IMPROVEMENT IN SASH-HOLDER.

The Schedule referred. to in these Letters Patent and making part of thesame'.

Y ball, or. wheel, in combination with a double, fixed inclined plane,for the purpose of supporting a windowsash inany required position, orlocking the same, .when closed. y

To enable others skilled in the art to make and use my invention, I willproceed t0 describe its construction and operation.

. Figure] is a front view of the case, made of iron, or

other suitable material, with the inclined planes A A and wheel B shownin dotted lines, slots G G, retaining-notch E, and semicircular notchF,the Wheel being made of' hard wood, rubber, iron, or part iron, and partrubber, o r any other suitable material.

The knob of the wheelis for thepurpose of operating the wheel from theoutside of the case, iig. 1, through slots G G. The notch E, fig. l, isfor the purpose of retainin the wheel Bin an inoperative position, sothat the sash may be moved freely up or down.

They can be-inade Without the retaining-notch, and

the sash will never, through inadvertence, be left unlocked. l

The semicircular notch F, fig. l, is provided, so that the wheel B,shank O, and knob D, (fig. 2,) can be made iu 'one piece, and be readilyplaced in position in the case, thus greatly facilitating themanufacture.

The inclined planes can be formed in the sash itself', in which case,only the front plate of the Wheel-case will` be required, or the casecan be made in a formsuitable to be mortised ntothe sash.

The operation is as follows: f The oase with wheel inserted beingattached to the sash in proper position, and the wheel B, by means ofknob D, placed, with shank O, in th'e retaining-notch E, the sash can beplaced in the required position, when, by pushing the wheel up, i-t willbecome wedged between the inclined plane and the sideof the Windowframe,and support the sash; on slightly raising the sash, the wheel will bereleased, and drop to the lower inclined plane, when, on lowering thesash, it will be locked down, without further attention.
